If `a` * `b = a^2+b^2` then the value of `2`*`4` is

If a*b=a^(2)+b^(2) then the value of (4*5)*3

If a^(*)b=a^(2)+b^(2), then the value of (4*5)*3 is a^(*)b=a^(2)+b^(2), then the value of (4*5)*3 is (4^(2)+5^(2))+3^(2)( ii )(4+5)^(2)+3^(2)41^(2)+3^(2)( iv) (4+5+3)^(2)

If a + b = 6 , a - b = 2 , then the value of 2 (a ^2 +b^2) is :

If the binary operation * on Z is defined by a*b=a^(2)-b^(2)+ab+4, then value of (2*3)*4 is 233( b ) 33 (c) 55 (d) -55

If a^(2) +b^(2) = x, ab = y then the value of (a^(4) +b^(4))/(a^(2) -ab sqrt(2) +b^(2)) is

If a+b+c=0&a^(2)+b^(2)+c^(2)=1 then the value of a^(4)+b^(4)+c^(4) is
